How MCP works
What is Spreadsheet Insight?
You have a CSV or Excel file and need a read of columns, odd rows, and chart ideas without building a dashboard. Spreadsheet Insight accepts CSV, TSV, XLS, XLSX (max 10 MB) and uses your Gemini API key. It does not create a Google Sheet.
Who it is for: analysts, operators, and founders with a table export. What it is not: a BI tool, REST/MCP, or Drive write.
What are common questions about Spreadsheet Insight?
Who is Spreadsheet Insight for?
Analysts, ops, and founders with a CSV or Excel export who want a first-pass brief.
What problem does it solve?
Column types, anomalies, and chart ideas from the file — without inventing a Sheet in Drive.
How do you use it?
Upload CSV/TSV/XLS/XLSX (10 MB), optional focus prompt, Gemini key, bot check, run. Check numbers in the file.
Do I need a Gemini API key?
Yes. Paste a Gemini API key from Google AI Studio. The key is sent only with that run and is not stored.
Is this REST or MCP?
No. This page is browser-only on toolyour.com. It is not on REST, SaaS API keys, MCP, or the npm SDK.
Does it write Google Sheets?
No. Markdown in the browser. Upload to Drive yourself if you need a Sheet.
Why did Excel fail on File Analyzer before?
The generic analyzer used to reject some spreadsheet types. This picker is CSV/TSV/XLS/XLSX. File Analyzer now accepts those types too for mixed jobs.
What are the key features of Spreadsheet Insight?
CSV and Excel
CSV, TSV, XLS, XLSX — 10 MB.
Column and type notes
What each field looks like from the file contents.
Anomalies and charts
Outliers and suggested chart types — still verify.
Optional focus
e.g. revenue by month, missing values.
How do you use Spreadsheet Insight?
Export a clean table
One header row helps. Remove empty junk sheets if you can.
Upload (10 MB)
CSV, TSV, XLS, or XLSX.
Optional focus
Tell Gemini what to look for.
Add Gemini key and run
Complete the bot check.
Reconcile totals
Trust the spreadsheet over the brief.
Who is the target audience?
Operators with CRM or billing CSVs, founders with a simple P&L export, marketers with ad export tables, students with lab data.
BI and warehouse teams still need their own tools. This is a brief, not a model.
What problems does it solve?
- “What columns do I even have?”
- Spotting empty or weird values in a first pass
- Ideas for charts before you build them
- Questions the table can answer vs. cannot
It does not join tables, fix types in the file, or run SQL.
Practical use cases
- First look at a new CRM export
- Anomaly notes on a monthly expenses CSV
- Chart ideas for a simple KPI sheet
- Teaching: “what questions does this table support?”
Need JSON instead? Use CSV to JSON under file conversion (API-backed). This insight tool is not.
Limits and honesty
10 MB. Multi-sheet workbooks may be incomplete. Numbers in the brief can be wrong.
Browser-only. Not REST, MCP, SDK, or Google Sheets.
